Alpha-Synuclein Dysregulation in Systemic Pathophysiology of Synucleinopathies

Area of Science:

• Neurodegenerative diseases
• Cell biology
• Immunology
• Hematology

Background:

• Alpha-synuclein (α-syn) is implicated in Parkinson's disease and Lewy body dementia.
• Pathophysiology involves α-syn aggregation, but accumulation mechanisms are unclear.
• Emerging research highlights α-syn's essential roles in homeostasis, particularly in hematopoietic and immune systems.

Purpose of the Study:

• To review recent advances in systemic synucleinopathies.
• To explore the interconnectedness of α-syn's roles across different organ systems.
• To highlight the potential for synergistic origins of synucleinopathies.

Main Methods:

• Literature review of recent studies on α-synuclein.
• Analysis of α-syn's function in normal homeostasis and disease.
• Examination of inter-systemic connections in synucleinopathies.

Main Results:

• α-synuclein plays vital roles in hematopoietic and immune cell function.
• α-syn deficiency leads to abnormal hematopoietic and immune cell phenotypes.
• Synucleinopathies may involve a dual pathology: α-syn toxicity and disruption of essential functions.

Conclusions:

• Understanding α-syn's systemic roles is crucial for developing effective therapies.
• Potential treatments must consider the risk of disrupting essential α-syn functions.
• Synucleinopathies may arise from interconnected systemic processes, suggesting novel therapeutic targets.
